本發明係關於一種焊料組成物。 This invention relates to a solder composition.
車輛(諸如汽車)之前窗及後窗通常包括位於玻璃內或位於玻璃上的電子元件。典型地,電子元件為天線或除霜器。為了向該電子元件提供電連接,向玻璃塗覆較小區域之金屬塗層以製得與電子元件電連接之金屬化表面。隨後,將電連接器焊接於金屬化表面上。通常用含鉛(Pb)焊料將電(亦即電源)連接器焊接至玻璃之金屬化表面上。由於各個國家對環境之關注及/或法規要求,故大多數產業目前在焊接應用中使用或計劃使用無鉛焊料。一些產業中所用的常見無鉛焊料含有較高錫(Sn)含量,諸如大於80%錫。如本文中所描述之汽車玻璃上所用的無鉛焊料揭示於在2001年7月3日頒予John Pereira之美國專利第6,253,988號中(下文中稱為「Pereira」)。在數種無鉛焊料中,Pereira揭示一種具有64.35重量%至65.65重量%銦(In)、29.7重量%至30.3重量%錫(Sn)、4.05重量%至4.95重量% 銀(Ag)、0.25重量%至0.75重量%銅(Cu)之焊料組成物(下文中稱為「65銦焊料(65 Indium Solder)」)。 Front and rear windows of vehicles, such as automobiles, typically include electronic components located within or on the glass. Typically, the electronic component is an antenna or a defroster. To provide an electrical connection to the electronic component, a thin metal coating is applied to the glass to produce a metallized surface that is electrically connected to the electronic component. Subsequently, the electrical connector is soldered to the metallized surface. The electrical (ie, power) connector is typically soldered to the metallized surface of the glass using lead (Pb) solder. Due to environmental concerns and/or regulatory requirements in various countries, most industries currently use or plan to use lead-free solder in soldering applications. Common lead-free solders used in some industries contain higher tin (Sn) content, such as greater than 80% tin. A lead-free solder for use on automotive glass as described herein is disclosed in U.S. Patent No. 6,253,988 (hereinafter referred to as "Pereira") issued to John Pereira on July 3, 2001. Among several lead-free solders, Pereira discloses a type having 64.35 wt% to 65.65 wt% indium (In), 29.7% wt% to 30.3 wt% tin (Sn), 4.05 wt% to 4.95 wt%. Silver (Ag), a solder composition of 0.25 wt% to 0.75 wt% copper (Cu) (hereinafter referred to as "65 Indium Solder").
當將元件焊接至汽車玻璃上時,遭遇到在其他應用中所不存在的困難。汽車玻璃易碎且通常錫含量較高,適用於其他應用之無鉛焊料可典型地致使汽車玻璃開裂。儘管諸如陶瓷及矽之材料可能似乎在某些方面與汽車玻璃類似,但適用於焊接陶瓷或矽元件之一些焊料不適用於焊接至汽車玻璃上。焊接兩種在熱膨脹係數(CTE)方面具有實質性差異的材料(在此情形中諸如玻璃及銅),在焊點冷卻期間或在後續溫度偏離期間對焊料施加應力。焊料組成物需要具有足夠低的熔點(液相線)從而不會在焊接製程期間導致汽車玻璃開裂,此係因為較高熔點及相應較高的處理溫度增強CTE失配之不利效應,在冷卻期間施加較高應力。然而,焊料組成物之熔點需要足夠高以便在汽車正常使用期間(例如當汽車在太陽下車窗接近太陽或在其他極端惡劣環境條件下時)不會熔融。然而,含銦焊料通常比其他焊料具有低得多的熔點。舉例而言,65銦焊料與鉛焊料160℃相比具有109℃之固相線溫度,且與鉛焊料224℃相比具有127℃之液相線溫度。一些車輛製造商需要將能夠經受得住高溫(例如對於一個原始設備製造商(OEM)為110℃且對於另一者為120℃)且在性能方面無任何劣化的玻璃製品。 When the component is soldered to the automotive glass, difficulties that are not present in other applications are encountered. Automotive glass is fragile and typically has a high tin content, and lead-free solders suitable for other applications typically cause cracking of automotive glass. While materials such as ceramics and tantalum may appear similar in some respects to automotive glass, some solders suitable for soldering ceramic or tantalum components are not suitable for soldering to automotive glass. Two materials that have substantial differences in coefficient of thermal expansion (CTE), such as glass and copper, are welded, stress is applied to the solder during solder joint cooling or during subsequent temperature deviations. The solder composition needs to have a sufficiently low melting point (liquidus) so as not to cause cracking of the automotive glass during the soldering process, because the higher melting point and correspondingly higher processing temperatures enhance the adverse effects of CTE mismatch during cooling Apply a higher stress. However, the melting point of the solder composition needs to be high enough to not melt during normal use of the vehicle (eg, when the car is approaching the sun in the sun or under other extreme environmental conditions). However, indium containing solders typically have a much lower melting point than other solders. For example, 65 indium solder has a solidus temperature of 109 ° C compared to lead solder at 160 ° C and a liquidus temperature of 127 ° C compared to lead solder 224 ° C. Some vehicle manufacturers require glass articles that can withstand high temperatures (eg, 110 ° C for one original equipment manufacturer (OEM) and 120 ° C for the other) without any degradation in performance.
因此,存在對適用於玻璃之相較於目前可用組成物可經受更高高溫同時提供此應用領域之所有其他所需性質之無鉛焊料組成物的需要。 Accordingly, a need exists for a lead-free solder composition suitable for use in glass that can withstand higher temperatures than currently available compositions while providing all of the other desirable properties of this application.

圖3B中所示之形成上述焊料組成物20之另一方法200包括 在步驟210在高溫熔爐鍋(諸如感應加熱熔錫鍋(例如S.M.Manfredy,型號N.481))中加熱所需量之錫(Sn)直至錫完全熔融。感應加熱熔錫鍋為適宜用於將相對較小批量焊料加熱至高溫的熔爐,但其需要隨後進行在鍋中添加成分並攪拌熔融混合物,同時出於安全原因關掉電流(加熱)。在步驟220,關掉鍋且所需量之鎳(Ni)以較佳3/16"見方厚度約0.010"之薄片形式添加。下文所述之所有其他金屬均可以鑄錠形式添加。觀察到,在攪拌下,鎳薄片黏附於熔融混合物上且相較於鎳粉更易於熔融成溶液,且將鎳熔融成溶液相對困難之部分原因在於鎳為此焊料組成物中熔點最高的金屬(熔點1455℃)。在攪拌之後,鎳在步驟230成為溶液,打開鍋至高熱持續約10分鐘,直至熔融溫度達到約1500℉。隨後,在步驟240,再次關掉鍋且添加所需量之銅(Cu)、銀(Ag)、銦(In)、銻(Sb)及視情況選用之鍺(Ge)且在步驟250攪拌,直至其熔融成金屬溶液。隨後,在步驟255打 開鍋至高熱,直至熔融溫度達到約1400℉。在步驟260關掉鍋,且添加所需(視情況選用之)量之鋅(Zn)且攪拌直至熔融成金屬溶液。隨後打開鍋至低熱持續幾分鐘以平衡金屬溶液,此後合金備用於傾注成鑄錠。觀察到鋅需要作為最後成分添加,原因在於其熔點相對較低(熔點419.5℃)且含鋅金屬溶液過度的曝露於高溫可導致鋅自金屬溶液中汽化。 Another method 200 of forming the solder composition 20 shown in FIG. 3B includes The desired amount of tin (Sn) is heated in a high temperature furnace pot (such as an induction heating pot (e.g., S.M. Manfredy, model number N.481)) in step 210 until the tin is completely melted. Induction heating tin pots are furnaces suitable for heating relatively small batches of solder to high temperatures, but which require subsequent addition of ingredients to the pot and agitation of the molten mixture while turning off the current (heating) for safety reasons. At step 220, the pan is turned off and the desired amount of nickel (Ni) is added in the form of a sheet having a preferred 3/16" square thickness of about 0.010". All other metals described below can be added in the form of ingots. It was observed that under stirring, the nickel flakes adhered to the molten mixture and were more easily melted into a solution than the nickel powder, and the reason why it was relatively difficult to melt the nickel into a solution was that nickel was the metal having the highest melting point in the solder composition ( Melting point 1455 ° C). After stirring, the nickel becomes a solution in step 230, and the pot is opened to high heat for about 10 minutes until the melting temperature reaches about 1500 °F. Subsequently, in step 240, the pot is turned off again and the required amount of copper (Cu), silver (Ag), indium (In), antimony (Sb) and, optionally, germanium (Ge) are added and stirred at step 250, Until it melts into a metal solution. Then, at step 255 Turn the pot to high heat until the melting temperature reaches about 1400 °F. The pot is turned off at step 260 and the desired (as appropriate) amount of zinc (Zn) is added and stirred until molten into a metal solution. The pan is then opened to low heat for a few minutes to equilibrate the metal solution, after which the alloy is ready for pouring into an ingot. It was observed that zinc needs to be added as a final component because its melting point is relatively low (melting point 419.5 ° C) and excessive exposure of the zinc-containing metal solution to high temperatures can cause zinc to vaporize from the metal solution.
元素在焊料組成物中之作用 The role of elements in solder composition
本發明之焊料組成物為一種無鉛合金,其提供較高操作溫度以及在強度及延性方面之機械性質及本發明應用中所需之在潤濕及穩定性方面的物理性質,同時提供所需可製造性。所需可製造性包括能夠實現足夠低之製程溫度,使得常在焊接含銀金屬化電接點表面時發生的製造易出現缺陷或故障及銀浸出(除去)現象減少或消除。此係藉由用銻、銅、鎳、銀、錫及視情況選用之鍺及鋅冶金合金化或沈澱或分散之銦基材料來實現。 The solder composition of the present invention is a lead-free alloy that provides higher operating temperatures and mechanical properties in terms of strength and ductility as well as physical properties in terms of wetting and stability required in the application of the present invention, while providing the desired Manufacturability. The manufacturability required includes the ability to achieve sufficiently low process temperatures such that manufacturing defects or failures and silver leaching (removal) phenomena that occur when soldering silver-containing metallized electrical contact surfaces are often reduced or eliminated. This is achieved by using bismuth, copper, nickel, silver, tin, and optionally zinc and metallurgical alloying or precipitation or dispersion of indium-based materials.
鎳及銅與其他元素組合有助於總體性能(包括所需之處理溫度升高)且亦有助於在指定製程條件下的機械性質。鎳及銅即使以少量(諸如0.03重量%)添加亦可有效。此等量比一般公認之鎳雜質含量(0.01%)大且比並不包括用銅電路焊接至印刷電路板上之應用中一般公認之銅雜質含量大。銻與其他元素組合有助於獲得所要溫度範圍。銻即使以少量(諸如0.1重量%)添加亦可有效。鋅與其他元素組合有助於增強合金強度而不實質上降低處理溫度。鋅即使以少量(諸如0.3重量%)添加亦可有效,其比一般公認之鋅雜質含量(0.003%)大。鍺與其他元素組合可有助於焊料組成物之可處理性,此歸因於其抗氧化性,但在一些情況下鍺在組成物中可能不易偵測到。鍺即使以少量(諸如0.01重量%或更低)添加亦可有效。 The combination of nickel and copper with other elements contributes to overall performance (including the required increase in processing temperature) and also contributes to mechanical properties under specified process conditions. Nickel and copper can be effectively added even in a small amount (such as 0.03% by weight). These amounts are greater than the generally accepted nickel impurity content (0.01%) and are generally greater than the generally accepted copper impurity content in applications that do not include soldering to printed circuit boards with copper circuitry. The combination of 锑 and other elements helps to achieve the desired temperature range. It is effective even if it is added in a small amount (such as 0.1% by weight). The combination of zinc with other elements helps to enhance the strength of the alloy without substantially reducing the processing temperature. Zinc can be effectively added even in a small amount (such as 0.3% by weight), which is larger than the generally recognized zinc impurity content (0.003%). The combination of cerium with other elements can contribute to the handleability of the solder composition due to its oxidation resistance, but in some cases bismuth may not be readily detectable in the composition. It is effective even if it is added in a small amount (such as 0.01% by weight or less).
